Embodiment 1

[0020] like figure 1 , figure 2 As shown, the special fixture used for clamping the collar includes a fixture seat, slide rail 1, adjusting screw 2, moving block 3, and clamping block 4. The lower end of slide rail 1 is installed on the fixture seat, and the upper end of slide rail 1 is clamped On the concave edge of the lower end of the moving block 3 , the lower end of the clamping block 4 presses on the concave edge of the upper end of the moving block 3 , and the adjusting screw 2 is engaged with the moving block 3 .

[0021] The clamping surface of the clamping block 4 is composed of three semi-cylindrical surfaces with different diameters, the diameters of the three semi-cylindrical surfaces are 80mm, 90mm, and 80mm respectively, and the clamping block 4 is on the clamping surface Inlaid tungsten carbide-based cemented carbide.

Embodiment 2

[0023] like figure 1 , figure 2 As shown, the special fixture used for clamping the collar includes a fixture seat, slide rail 1, adjusting screw 2, moving block 3, and clamping block 4. The lower end of slide rail 1 is installed on the fixture seat, and the upper end of slide rail 1 is clamped On the concave edge of the lower end of the moving block 3 , the lower end of the clamping block 4 presses on the concave edge of the upper end of the moving block 3 , and the adjusting screw 2 is engaged with the moving block 3 .

[0024] The clamping surface of the clamping block 4 is composed of three semi-cylindrical surfaces with different diameters, the diameters of the three semi-cylindrical surfaces are 40mm, 50mm, and 35mm respectively, and the clamping block 4 is on the clamping surface. Inlaid titanium carbonitride-based cemented carbide.

Abstract

The invention discloses a special clamp for clamping a collar and belongs to the field of machine tool clamps. The special clamp for clamping the collar comprises a clamp base, a sliding rail, an adjusting screw, a movable block and a clamping block, wherein the lower end of the sliding rail is arranged on the clamp base, the upper end of the sliding rail is clamped onto the concave edge of the lower end of the movable block, the lower end of the clamping block is pressed onto the concave edge of the upper end of the movable block, the adjusting screw is meshed with the movable block, the clamping face of the clamping block is composed of three semi-cylindrical surfaces with different diameters, and the diameters of the semi-cylindrical surfaces are the same as those of corresponding workpieces respectively. According to the special clamp for clamping the collar, the problems that shaft parts with collars can not be reliably clamped through an existing universal clamp, and the clamping force is not easy to control are solved. The special clamp for clamping the collar has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

technical field [0001] The invention belongs to the field of machine tool fixtures, and more specifically relates to a special fixture for clamping collars. Background technique [0002] In the machinery manufacturing industry, lathes, especially milling machines, are widely used to process disc or shaft parts. When processing such parts, there are many parts that need to use the end face or inner hole as the positioning clamping surface to perform cutting processes such as outer circle, end face, thread and axial cutting. For single-piece, small-batch, and large-volume workpiece processing, positioning and clamping can generally be realized directly on the machine tool table through adjustment, and then the position of the part can be determined by setting the machining coordinate system. For a certain batch of parts, it is necessary to reduce the labor intensity, reduce the auxiliary time of part processing, and improve production efficiency by selecting relevant special ...
